St. Mary's County has a central landfill and several convenience centers that are located throughout the county. The convenience centers are intended for homeowners to drop off their household trash and materials to be recycled. There is no charge for county residents.

Commercial haulers and homeowners who need to dispose of larger items such as tires, old appliances, brush, and constructions materials need to go to the main St. Andrew's landfill. There is a charge for all vehicles. Hazardous materials are also collected on certain dates throughout the year. Call the main landfill for information on the next collection date.

The St. Andrew's landfill also offers free mulch. Bring a shovel or pitchfork so that you can load your vehicle. We suggest that you call the landfill first to make sure that they have mulch available.

This is the main landfill for St. Mary's County. The St. Andrews Landfill Facility is located on St. Andrews Church Road, MD Route 4, approximately ½ of a mile south of the intersection with MD Route 235 on the left. Normal operating hours are 8 a.m. to 4:30 p.m. Monday–Saturday except holidays. Schedules may change based on bad weather and holidays. Please check the website to confirm the hours.

Mulch is available free to the public throughout the year as it becomes available. Mulch is self-service. Be sure to bring tools for loading (pitchfork, broad shovel, etc.) and a tarp to cover any open load.
